The Sun gives us light and heat, sustaining life on Earth. ... This uneven rotation, coupled with the churning of the upper layers, might well be what produces (by a "dynamo mechanism", described in a later section) regions of intense magnetic field, seen by observers on Earth as dark sunspots. ... Near sunspots those streamers seem to be shaped by the Sun's magnetic field lines, and above the Sun's poles they suggest field lines rising from twin magnetic poles like those of the Earth. ...

... On the morning of Thursday, 26 February, amid the Gal pagos Islands, the Sun will fade from view. Not the culmination of ancient prophecy, but none less mystical, Earth's small Moon will be executing a slow slide past the enormous Sun. ...

... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...

... An unusual type of solar eclipse occurred last week. Usually it is the Earth's Moon that eclipses the Sun. Last week, for the first time in over 100 years, the planet Venus took a turn. ... Enjoying the 2004 Transit of Venus from Stuttgart, Germany, astronomer Stefan Seip recorded this fascinating, detailed image of the Sun. ... With Venus in transit at the Sun's edge on June 8th, astronomers captured this tantalizing close-up view of the bright solar surface and partially silhouetted disk. ...

... Fig. ... One of these is a pink-coloured solar prominence, a tongue of incandescent hydrogen gas spewing out of the obstructed solar disc, visible at the 2 o'clock position. ... Such an eclipse was predicted to be visible from deep within the Asian continent on the 1st August 2008. ... A pink-coloured prominence was visible right from the onset (Fig. 1), while several streamers appeared to emanate from the obstructed solar disk throughout the event (Fig. ...

... 2010 June 28 . A Partial Lunar Eclipse . ... Explanation: What's happened to the Moon? This past weekend, once again, part of the Moon moved through the Earth's shadow. ... Pictured above, the face of a full moon is partly blocked by Earth's clouds, and partly darkened on the upper right by Earth's umbral shadow . Clouds permitting, the partial lunar eclipse was visible from the half of the Earth facing the Moon at the time of the eclipse , which included much of Earth's Pacific Rim . ...

Educator's Guide to Eclipses . ... In a solar eclipse you observe the Sun (using only safe methods, of course). ... In a lunar eclipse you observe the Moon. ... Because of the geometry described below, you can only view a solar eclipse when the Sun is up, and the Moon is nowhere to be seen. ... Eclipses occur when the Sun, Earth and Moon line up. ... In a solar eclipse the Moon passes directly in front of the Sun. ... In a lunar eclipse the Moon moves into Earth's shadow. ...

UC Santa Cruz Press Release: Astronomers discover an enormous halo of red giant stars around Andromeda 4/1/08 10:54 PM January 7, 2007 Contact: Tim Stephens (831) 459-2495; stephens@ucsc.edu Astronomers discover an enormous halo of red giant stars around Andromeda Astronomers have found an enormous halo of stars bound to the Andromeda galaxy and extending far beyond the swirling disk seen in images of the famous galaxy, our nearest large galactic neighbor. ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

... We present a computer program for modelling energy flux distribution and light curves of eclipsing binaries from far ultraviolet to infrared regions. The Roche model is assumed. Proximity effects of components (reflection of radiation and surface gravity darkening) are taken into account. ...

Solar Eclipses Notice that both the Sun and the Moon appear in the sky to be about the same size: half of a degree. ... The Earth would cast a shadow on the Moon when they were all three lined up. When the Moon blocks the Sun, we call it a solar eclipse. The other eclipse is when the Sun-EarthMoon lineup is in effect, and the Earth blocks the Moon. ... Lunar eclipses, however, are easier to see, since the shadow of the Earth on the Moon is quite large. ...

... Bad Astronomy . ... This first Snack of the year 2000 (yes, I am one of those who says the Millennium begins in 2001) will talk a little about a wonderful event: a total lunar eclipse. On the evening of Thursday, January 20 (or the early morning Friday, January 21 if you lives east of England) the Moon will go undergo one of the best eclipses it can. ... The Moon stays in the Earth's shadow in a lunar eclipse longer the Earth stays in the Moon's shadow during a solar eclipse. ... 2008 Phil Plait. ...

... Astronomers once thought Pluto's atmosphere would condense down to the surface as it moved away from the Sun. Can that still be true, and if so, is that causing the surface features we now see? ... This is almost certainly because the atmosphere which is nitrogen, like Earth s atmosphere is also frozen as ice on the surface. ... Get instant access to subscriber content on Astronomy.com! ...

... Planets . ... Stars . Exoplanets . ... Most exoplanets so far discovered fall into the category of тАШhot JupitersтАЩ, these are giant planets orbiting very close to their parent star. ... Note that we have discovered so many hot Jupiters because they are the easiest type of planet to find, they are not necessarily particularly common in the galaxy. ... Subsequently several similar hot and€а fuzzy worlds have been discovered the same way, proving this that this planet is not a one-off oddball. ...
